BARGE MOTIONS IN WAVES
Available from Stewart Technology Associates
We developed STA BARMOT for STA for preliminary calculation of the natural periods and RAOs (response amplitude operators) of prismatic (or roughly prismatic) marine barges. The RAOs are produced in a form suitable for direct input to OrcaFlex.
Since the roll response of marine barges is generally non-linear, meaning that the roll RAO changes with increasing wave height, the program permits the user to specify the wave height of interest and adjusts the roll amplitude RAO component accordingly. An additional roll damping term can also be specified to account for bilge keels and other appendages.
Recent additions to OrcaFlex now enable us to produce full diffraction solutions for the motions analysis of any vessel in waves.
